  note: This error originates from a subprocess, and is likely not a problem with pip.
  ERROR: Failed building wheel for dpss
Failed to build dpss
ERROR: Could not build wheels for dpss, which is required to install pyproject.toml-based projects

What I tried:

• Installing and reinstalling Rust
• Manually installing cffi (despite it already having been installed prior to installing dpss)
• Installing package maturin from PyPI

I haven't checked whether this library works with Python 3.12. I'll investigate this issue.
